T-Mobile Launches Beta for Free Real-Time Call Translation on Any Phone

[MacRumors]

T-Mobile today announced a new live translation feature that allows conversations to be translated in real-time when calling someone from any phone on the T-Mobile network.

Live translation does not require any apps, and it is a free service that T-Mobile is offering in a beta capacity. T-Mobile users can sign up to test live translation on the T-Mobile website, with limited spots available.

The feature works with more than 50 languages, and voice conversations are translated for each speaker "almost instantly." T-Mobile says that users can speak how they normally do on calls, with live translation detecting the languages and voices that are speaking for a natural conversation.

Live translation is built into the T-Mobile network, so it works with any phone on T-Mobile, from iPhones to flip phones. T-Mobile users can even call landlines and get translation capabilities because only one phone connected to the call has to be on T-Mobile for translation to work.

To use live translation, T-Mobile users will need to sign up for the beta. From there, when on a call, pressing * 87 * on the keypad will initiate the live translation process.

Apple rolled out a translation feature for phone calls with iOS 26, but T-Mobile's version does not require participants to have an iPhone, and it covers more languages.

While live translation is free during the beta testing process, there could be a fee associated in the future. T-Mobile has not mentioned what it will cost when the beta ends.

doesn't apple already have this with air pods?

Not over the phone network I think, but yes to in person conversations

Which provider is T-Mobile funneling your calls through to transcribe and translate the calls in realtime?

They only seem to say "translations are AI generated and accuracy is not guaranteed" in the fine print.

Who's getting your phone calls without two-party-consent for training data?

 

[Viridian5]

I signed up, we’ll see if I get picked. Imagine this technology on a global scale and how helpful it would be

Yay, everyone can now better understand those people calling from call centers in (insert nation)

I wonder what Duolingo is for...

T-Mobile says they're not using customer phone conversations for training. They say they have their own "internal-only test calls" for training the unnamed AI.

T-Mobile Bringing Live Translation to Phone Calls Using AI

An AI agent on T-Mobile's network can translate between languages as you and the other person talk. And you don't need special phone hardware to do it.

www.cnet.com

When I asked Saw whether conversations are recorded, even during the beta period, he said that kind of fine-tuning is being done using millions of internal-only test calls. "We don't listen to customers' calls, and [the AI models] are not trained on customers' data," said Saw, noting that the service meets all FCC guidelines for privacy.

Exactly which AI translation models are being used, or which partner companies are providing them, is something Saw declined to share. He did confirm that T-Mobile is working with several AI companies, but "we're not going to name them because we love them all the same."

Saw noted that the way T-Mobile's network is designed as a platform has the advantage of being able to plug in updated AI translation models, run an upgrade overnight and make it available to hundreds of millions of phones.

While I know this will eventually end up being robust enough for general communication, it’s also sad that it will make so many people not even put in the minimal effort to learn a foreign language or appreciate other cultures.

 

[Gengar]

Just more features that are already built into iPhones on the latest iOS that they hope to charge for one day (like satellite connectivity).

 

[Sputman99]

I do hope the call transcripts aren’t stored anywhere - imagine the security issues with that

Doesn’t work very well. Unless… you… talk… very… slowly…

 

[Nermal]

Maybe I'm a cynic, or paranoid, but this makes it seem that the phone network can no longer be trusted to get your voice from one end to the other. What you say might not be what the other end hears.

 

[nutmac]

This feature, like T-Mobile’s satellite service before it, will be a paid feature, possibly free on the higher priced plans.

Apple users should use the free Live Translation feature. You can invoke it from "More" menu while on the call (you don't need to use AirPods to use this feature).

 

[macduke]

I'm just some jackass on the internet, but this sounds like they're sourcing millions of their multilingual customers to train AI datasets for God knows who. I don't trust this one bit. But then again, I don't even trust regular phone lines anymore since that company that was paying users to call their friends and family and the app was recording the conversations for AI training. I don't trust anything that isn't end to end encrypted.

 

[Audentia]

Is this not a huge privacy concern? I'm amazed there's not outcry, or that they are marketing this like such casual feature

 

[applicious84]

Lol. I hope it can also translate bored Americans or folks in the south

 

[Hogswarts]

The cost is your privacy.

 

[garranhado]

I'm amazed how Apple hasn't implemented something like that for real-time calls, audio and video yet. Subtiles are things of the past.

 

[tennisproha]

This is just a blatant privacy violation. T-Mobile will be wiretapping your conversation and will definitely be selling it to data brokers.

It'll definitely disincentivize learning another language, but I think it'll make other cultures more accessible. Communication is the key to appreciating another culture but language gets in the way. This kind of tech makes it so much easier for people from different cultures to connect and that leads to better understanding and appreciation. It's very cool. Yet another step closer to a human culture.

 

[Makosuke]

This is a cool feature and unlike a lot of these things genuinely useful.

That said, as much better as auto translation has gotten, even with clear, grammatically-correct writing there are still significant errors and once you bring slang or casual language into it I’ve seen some horribly inaccurate botches. So, “just talk naturally” could be a pretty dangerous instruction if the people on both ends don’t temper their expectations in terms of mistranslation—I can imagine deeply offensive or destructive mistakes if anything sensitive or important were being discussed.

Part of the issue is if the auto translator DOES do a good job of making it sound grammatically correct and “natural”—if you are reading a machine translation and it has janky grammar or awkward language you get a feel that maybe you might not be getting an accurate translation, but if it reads smoothly then you will just assume it’s accurate.

It’s basically a realtime conversational version of LLM hallucination—the confident natural language responses lull you into a false sense of security, and presumably TMo’s translation software will try to fill in something plausible whether it’s accurately parsing the input or not.

If you worry about that why not worry they are storing the audio and could have been for years.

That's exactly what I was wondering. If the network can listen in on calls, that's a bit disturbing.

Privacy has been an illusion for a very long time.
